Everything you want to know and never dared to ask. A practical approach to employing challenge-based learning in engineering ethics
Challenge-based learning (CBL) for engineering ethics tasks students with identifying ethical challenges in cooperation with an external partner, e.g., a technology company. As many best-practice parameters of such courses remain unclear, this contribution focuses on a teacher-centric introduction into deploying CBL for engineering ethics. Taking Goodlad’s curriculum typology as a point of departure, we discuss practical issues in devising, maintaining and evaluating CBL courses for engineering ethics both in terms of the temporal dimension (before, during and after the course) as well as in terms of the people involved. We will discuss selecting learning objectives, forms of knowledge acquisition, supporting self-organization, and fostering discursive etiquette, as well as cooperative, yet critical attitudes. Additionally, we will delve into strategic matters, e.g., ways to approach potential external partners and maintain fruitful cooperations
Responsible and Regulatory Conform Machine Learning for Medicine: A Survey of Challenges and Solutions
Machine learning is expected to fuel significant improvements in medical
care. To ensure that fundamental principles such as beneficence, respect for
human autonomy, prevention of harm, justice, privacy, and transparency are
respected, medical machine learning systems must be developed responsibly. Many
high-level declarations of ethical principles have been put forth for this
purpose, but there is a severe lack of technical guidelines explicating the
practical consequences for medical machine learning. Similarly, there is
currently considerable uncertainty regarding the exact regulatory requirements
placed upon medical machine learning systems. This survey provides an overview
of the technical and procedural challenges involved in creating medical machine
learning systems responsibly and in conformity with existing regulations, as
well as possible solutions to address these challenges. First, a brief review
of existing regulations affecting medical machine learning is provided, showing
that properties such as safety, robustness, reliability, privacy, security,
transparency, explainability, and nondiscrimination are all demanded already by
existing law and regulations - albeit, in many cases, to an uncertain degree.
Next, the key technical obstacles to achieving these desirable properties are
discussed, as well as important techniques to overcome these obstacles in the
medical context. We notice that distribution shift, spurious correlations,
model underspecification, uncertainty quantification, and data scarcity
represent severe challenges in the medical context. Promising solution
approaches include the use of large and representative datasets and federated
learning as a means to that end, the careful exploitation of domain knowledge,
the use of inherently transparent models, comprehensive out-of-distribution
model testing and verification, as well as algorithmic impact assessments
